关于定语从句中what和where，in which 的用法差异

Posted 2023-05-04

参考技术A 1.
in
后面接句子，所以是名词性从句，而句子少主语所以用连接代词what。which在名词性从句中表示哪一个
意思不对。此句不是定从所以不要看错了。
2.
if
从句中travel
是不及物动词，由where引导的从句做地点状语，意思是旅行的地方的风俗和自己的风俗不同。when表示时间，where表示地点。旅游的地点风俗不同所以不选when。

关于which的用法及解释

参考技术A

　　which的用法在英语学习中是比较重要的一个知识点，重要就说明必须要掌握。接下来我在这里给大家带来which的用法，我们一起来看看吧!

　　which的用法

　　1、在后置的非限制性定语从句中代替上文出现的事物或情况(单数或复数)。

　　2、在问句中作为疑问代词，在名词从句中作为连接代词用，其含义为“哪个、哪些”。

　　3、如果非限制性定语从句的先行词不是指主句内容，而是指具体的人、时间、地点，则不用which。

　　一、关系代词that 和which 在定语从句中作主语和宾语，放在先行词和定语从句之间，起联系作用。指物时，一般情况下可互换。如： Here is the pen that/which you lost yesterday.(that/which 指物作宾语) A plane is a machine that/which can fly.(that/which 指物，作主语) He is the most careful boy that I know.(that 指人,作宾语) The man that works in this room is a chemist.(that 指人,作主语)

　　二、that,which 在从句中作主语时，不能省略。作宾语时在口语中和非正式问题中经常省略。如上例1 和中的that,which 都可省略。

　　三、关系代词在主语从句中作主语时，从句的谓语动词的人称和数须和先行词一致。 Wheat is a plant that/which is grown in the north of China.

　　四、在定语从句中，关系代词that 和which 指物时，一般没有区别，但下列几种情况中不能互换：

　　只能用that 的情况：

　　a)先行词为 all,everything,nothing,anything,little 等不定代词时(something 后也可用which)： Is there anything (that) I can do for you in town? That’s all (that) I know.

　　b) 先行词被序数词所修饰时： The first thing (that) we should do is to work out a plan.

　　c) 先行词被形容词最高级所修饰时： This is one of the most exciting football games (that) I have ever seen. The nanjing yangtse river bridge is the longest bridge (that) they have ever seen.

　　d) 先行词 被only,very,no,any,same,little,one of 等词所修饰时： This is the only thing (that) we can do now. He gave me the same pen (that) he borrowed from me. Do you have any books that were written by Lu Xun? This is the very book (that) I want to read.

　　e) 当先行词中既有人又有物时： The man and the car (that) you want to see are all here. 你相见的人和车都在这里。

　　f) that 可指人，which 则不能： Who is the man that is reading the newspaper over there?

　　g) 在 “the time when”等结构和某些时间状语中，when 常被that 代替，而且that 往往省略： I may leave here any time I want to. During the time I was there I visited him twice.

　　h)way 后面可根由that 引导的定语从句，但that 一般都省略： That was the way she looked after us.

　　在下列情况中，只能用which:

　　a) 放在介词后面做介词宾语时： This is the question about which we’ve had so much discussion. 但是，如把介词放在从句的后部，这时which 就可换为that 并常省略。如上例可改为： This is the question (that) we’ve had so much discussion about.

　　b) 在非限制性定语从句，无论指物指人，都不能用that。指物时，只能用which 和其他关系代词。如： All the books there,which have beautiful pictures in them,were written by him.

　　which的相关解释

　　pron.哪一个; 哪一些; 哪个; 那，指前面提到的事物

　　adj.哪一个; 哪一些;

　　which与that的用法区别

　　两者都可指物，常可互换。其区别主要在于：

　　1. 引导非限制性定语从句时，通常要用which：

　　The current, which is very rapid, makes the river dangerous. 水流湍急，使这条河很危险。

　　He has to work on Sundays, which he doesn’t like. 他得在星期天工作，他是不喜欢这样的。

　　The London team, which played so well last season, has done badly this season. 伦敦队上一个季度打得很好，这个季度却打得很差。

　　2. 直接放在介词后作宾语时，通常要用which：

　　She may be late, in which case we ought to wait for her. 她可能晚到，那样我们就要等等她。

　　The documents for which they were searching have been recovered. 他们找寻的文件已找到了。

　　This morning some port wine came, for which I have to thank you. 今天早上送来一些波尔图葡萄酒，为此我得向你道谢。

　　注：有时“介词+which”引导的定语从句可以转换成“介词+which+不定式”结构：

　　He had only the long nights in which he could study. =He had only the long nights in which to study. 他只有漫漫长夜可用来学习。

　　He had a couple of revolvers with which he could defend himself.= He had a couple of revolvers with which to defend himself. 他只有一两把手用来自卫。

　　3. 当先行词是下列不定代词或被它们修饰时much, little, none, all, few, every(thing), any(thing), no(thing) 等时，通常用that：

　　All that she lacked was training. 她缺的只是训练。

　　Have you everything that you need? 你需要的东西都有了吗?

　　The sleeping man’s subconscious mind retained everything that was said around him. 这位酣睡的人头脑的下意识能记住他周围的人说的话。

　　She would never do anything that was not approved of by her parents. 她父母不赞同的事她绝不会做。

　　4. 当先行词有the very, the only, the same 等修饰时，通常用that：

　　This is the only example that I know. 我知道的例子只有这一个。

　　Those are the very words that he used. 那是他的原话。

　　5. 当先行词有形容词最高级或序数词(包括last, next等)等修饰时，通常用that：

　　This is the best dictionary that I’ve ever used. 这是我用过的最好的词典。

　　The first thing that you should do is to work out a plan. 你应该做的第一件事是订个计划。

　　6. 当关系代词在定语从句中用作表语时，通常用that：

　　China is not the country (that) it was. 中国已不数去的中国了。

　　7. 当先行词是一个既指人又指物的并列词组时，通常用that：

　　They talked about the persons and things that most impressed them. 他们谈论了使他们印象最深的人和事。

　　8. 当要避免重复时：

　　Which is the course that we are to take? 我们选哪门课程?

　　which的例句

　　1.He lived on an invalidity pension which came as a weekly giro.

　　他靠每周领取的作为病残养老金的直接转账救济支票过日子。

　　2.Politicians want a lap-dog press which will uncritically report their propaganda.
